Growing your own tea?

I have recently been asked by the misses (Gardner of the family) if I would like to grow my own tea? (she is trying to get me involved in her hobby, which I think is great.) I have searched around and cannot find that much info on the subject.

from what i have read. these do well if you keep them indoors in front of a window.
I would imagine that is would be worth trying. our local nursery has a few that are matured. not sure of the price but google got me right to it once you use the proper name.
